Double Side Polished Co2+:MgAl2O4 Single Crystal Substrate


Nanocrystalline Co2+-doped magnesium aluminate spinel (MgAl2O4) has been synthesized for the first time from aqueous solution of metal nitrates containing citric acid as chelating agent by a sol-gel method. The gel was heat-treated at temperatures ranging from 710°C to 1000°C. The heated powder samples were characterized by X-ray diffraction analysis (XRD), transmission electron microscope (TEM), infrared (IR) and absorption spectroscopy. The results showed that the homogeneous nanocrystalline Co2+: MgAl2O4 could be obtained at the low temperature of 710°C. The optimal temperature is about 900°C and the average size of the powder grains is 50 nm or so. In the absorption spectrum, a broad absorption band from 1200 nm to 1600 nm was found, which indicated the existence of Co2+ in the tetrahedral sites because of the 4A2(4F) → 4T(4F) transition of Co2+.

Co2+:MgAl2O4 Single Crystal Substrate Brief Introduction:

  • Co2+:MgAl2O4 (Co2+:Spinel or Co:MALO) crystals is a new material for passive Q-switching in lasers emitting from 1.2 to 1.6 µm, in particular, for eye-safe 1.54 µm Er:glass laser, but also works at 1.44 µm and 1.34 µm wavelengths.
  • High absorption cross section (3.5 × 10-19cm2) permits Q-switching of Er:glass laser without intracavity focusing both with flash-lamp and diode-laser pumping.
  • Negligible excited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10.
  • We offer the high quality Co:Spinel crystals materials with high optical quality and uniform distribution of Co2+ in laser grade polishing and coatings.
Co2+:MgAl2O4 Feature:
  • Suitable for 1540 nm eye-safe lasers
  • High absorption section
  • Negligible excited state absorptio
  • High optical quality
  • Uniformly distributed Co
